Is psychology too WEIRD? That's what this episode's guest, psychologist Steven J. Heine suggested when he and his colleagues published a paper suggesting that psychology wasn't the study of the human mind, but the study of one kind of human mind, the sort generated by the kinds of brains that happen to be conveniently located near the places where research is usually conducted - North American college undergraduates. They called them the WEIRDest people in the world, short for Western, Education, Industrial, Rich, and Democratic - the kind of people who make up less than 15 percent of the world's population. In this episode, you'll learn why it took so long to figure out it was studying outliers, and what it means for the future of psychology.

In psychology, they call it naive realism, the tendency to believe that the other side is wrong because they are misinformed, that if they knew what you knew, they would change their minds to match yours.

According to Lee Ross, co-author of the new book, The Wisest One in the Room, this is the default position most humans take when processing a political opinion. When confronted with people who disagree, you tend to assume there must be a rational explanation. What we don't think, however, is maybe WE are the ones who are wrong. We never go into the debate hoping to be enlightened, only to crush our opponents.

Listen in this episode as legendary psychologist Lee Ross explains how to identify, avoid, and combat this most pernicious of cognitive mistakes.

"Science is wrong about everything, but you can trust it more than anything."

That's the assertion of psychologist Brian Nosek, director of the Center for Open Science, who is working to correct what he sees as the temporarily wayward path of psychology.

Currently, psychology is facing what some are calling a replication crisis. Much of the most headline-producing research in the last 20 years isn't standing up to attempts to reproduce its findings. Nosek wants to clean up the processes that have lead to this situation, and in this episode, you'll learn how.

In medical school they tell you half of what you are about to learn won't be true when you graduate - they just don't know which half. In every field of knowledge, half of what is true today will overturned, replaced, or refined at some point, and it turns out that we actually know when that will be for many things. In this episode, listen as author and scientist Sam Arbesman explains how understanding the half life of facts can lead to better lives, institutions, and, of course, better science.
